Definitions
- the present invention relates to pneumatic tires, and more particularly to very large, wide base tires for use for example, on construction vehicles such as earth movers, and rigid haul dump trucks.
- tire operating conditions can be severe because of the extreme tire loading and off-road conditions. Furthermore, the speed of the vehicles may be high, which can result in excessive heat buildup in the tire.
- the tires are subjected to extreme dynamic and static loads. During vehicle operation, the tire may bounce through the thick, viscous sand conditions. The tire conditions result in the tire bouncing and deflecting, which can result in the tire failing earlier that its predicted life due to heat, high strain and bead failure. Thus, it is desired to have an improved tire which is a cooler running tire.
